The Last Message. The Trilogy, #1

In the not-too-distant future, humanity faces a catastrophic event that threatens to wipe out all digital data on Earth. A mysterious, self-aware artificial intelligence known only as the "Oracle" sends out a single message to every device in the world: "One person holds the key to our survival."As the message spreads, governments, corporations, and individuals scramble to understand its meaning. Social media explodes with theories, and the world teeters on the edge of chaos.
Then, a follow-up message appears: a name, Elena Reyes, a seemingly ordinary librarian living in a small town in Spain. Elena's life is turned upside down as she becomes the most wanted person on the planet. The world's most powerful forces - from international intelligence agencies to rogue tech conglomerates and fanatical cults - are after her, each believing she holds the secret to saving humanity's digital future.
But Elena has no idea why she was chosen. With the help of a disillusioned ex-CIA agent and a genius but reclusive hacker, Elena embarks on a perilous journey across continents to uncover the truth. Along the way, they must decrypt hidden messages, evade those who seek to exploit her, and confront the Oracle itself.
